As a response to the problem of entering a large number of alternate symbols
for data requests from a particular feed Capital Flow 32 now has a function to
add a suffix and/or prefix to all stock and/or futures symbols in one pass. This
feature can be accessed in the Special menu in Capital Flow 32.

Many feeds require a prefix for a symbol to clarify what exchange lists the
contract or whether the contract is delayed or live. Examples include the
requirement by Aspen/DTN that delayed contracts be preceded by a "D_"
for delayed data. If you have signed up for delayed data for all futures, you
can use this function to add a "D_" to all futures. If, however, you
get live data for some futures exchanges, and delayed data for others, you are
probably better off editing the symbols manually. See the Aspen
Symbols page on this site for more information on manually editing the
Alternate Symbols.

The "Bulk Change" function simply creates an alternate symbol for a
specified exchange from the Capital Flow symbol (the one that you originally
activated, whether from the Activate Futures/Stocks menu or from the Activate
Custom function) preceded by the prefix you specify (if any) and followed by the
suffix (if any) that you specify. It is possible to change Stocks only, Futures
only, or Stocks and Futures, but checking the appropriate boxes. These new
Alternate Symbols will replace any existing Alternate Symbols for the selected
exchange that you may have entered previously.

After having made the bulk changes to Alternate Symbols, it may still be
necessary to add additional changes to selected symbols, such as the E-mini CME
contracts, which require an "@" symbol in front of the actual symbol,
or the "All Sessions" contracts, which require two "@"
symbols before the contract symbol. If you have delayed data, then, the final
symbol should be "D_@ESU2" for the delayed E-mini September 2002
S&P contract, or "D_@@USU2" for the delayed all session September
30 year US Bond contract.

For Capital Flow 3.7 it is necessary to change the symbols manually, using
the Utility / Edit Symbol function. We do not anticipate adding the above
mentioned feature to Capital Flow 3.7 because of the extensive time involved in
rebuilding that program.
